2x4 SPF Lumber

Spruce, Pine, and Fir, the three softwood species that make up SPF lumber products, are processed together due to similar appearance and properties. SPF represents the largest reserve of commercial softwood in Canada.

SPF is the most commonly used lumber for house construction (known as “2x4”) in North America due to its strength, light weight and ease in cutting and nailing. Kiln-dried to a maximum 19% moisture content, SPF is used primarily for wall framing, roof framing, roof trusses, floor joists and beams. In addition, certain grades are suitable for non-structural applications such as packaging and re-manufacturing.

Sizes: CLS SPF lumber is described by its nominal size, which differs from actual size.

Thickness: 1 inch and 2 inches (actual thickness is 19mm and 38mm).

Width: From 3 inches to 12 inches (actual width is 63mm to 285mm).

Length: Increments of two feet (0.6m), from 6 feet (1.8m) to 20 feet (6.0m). Packaged one length per bundle and wrapped for protection against moisture.
